The' present invention relates to grease guns particularly adapted for use with a grease tank wherein grease' is st ored under pressure, the object of the invention being to provide a device whereby the grease may be evenly and expeditiously sent to the variplis grease nipples of an automobile or the Another very important object of the invention resides in the provision of a grease gun of this nature which is simple in its construction, handy, easy to manipulate, thoroughly eliicient and reliable in operation, and otherwise well ada ted to the purpose for which it'is designefl With the above and numerous other objects in view as will appear' as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be,

hereinafter more fully described and claimed.

In the drawing: Figure 1 is a side'elevation of the gun em bodying the features of my invention showing the same coupled with a tank,

Figure 2 is a top plan view thereof,

F igure is a sectional view therethrough taken substantially on the line' 3 3 of F' ure 2,

igure 4 is a perspective view of the dispensing tube, and

Fi ure 5 is a sectional view taken substantially on the line 5-5 of Fi ure 2.

Referring to the drawing in etail it will be seen that the numeral 5 denotes a hollow elongated tube in one end of which is threaded a nipple 6 over which is adapted to be placed one end of a hose 7.

A check valve 8 is held against a seat in the nipple 6 by means of a spring 9. A later'- ally disposed internally threaded bore 10 is formed 1n the up r portion of the tube 5 in communication with the interior thereof and a tubular member 11 is threadedly engaged 45 therein. t

' vA tube 12 is slidable into the member 11.

A valve seat 14 is formed in the member 1:1` and a ball valve 15 is held against this valve by means of a spring 16. A stuing box 17 5 is engaged on the end of the member 11 and the tube 12 is slidable therethrough. A lever 20 is bifurcated at one endto straddle the member 1l and the ends of the furcations are pivoted yon a pin 21 extending through an extension 22 on the upper end of the grip 5.

A member 23 is secured to an intermedlate portion of the tube 12 by set screws 24 about which are rockable forward ends of links 25, the other ends of which are pivotally engaged by screws 26 with intermediate portions of the furcations of the lever 20.

A suitable coupling 27 is provided on the outer end of the tube 12 so that it will be engaged with the grease nipples of the automobile dependin upon the make thereof.

The inner en of, the tube has slots 28 formed therein. The letter T'denotes a tank to contain grease under pressure which is discharged through pi e P having a valve V thereon and couple 'with a hose 7. When tube 5 after the coupling 27 has been engaged it will be seen that the tubular member 11 is slid over the tube 12 thereby unseating the l valve'15 so that the grease mayepass through the slot 28 and through the tu 12 to grease the parts engaged with the coupling 27. lAs

- soon as suicient grease has been delivered to the parts then the lever 20 is released and the spring 16 issuliciently strong to press the valve 15 against the seat 14. y'

It is thought that the construction, operation, and vutility of this invention will now be iluite apparent to those skilled in this art wit out a more detailed description thereof.

'Ihe present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplilcation since in actual practice they attain the features of advantage enumerated as desirable in the statement of the invention and the i above description.

It will be apparent that changes in thedetails of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of theinvention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what -I claim as new is:

1. A device of the class described comprising a hollow grip, a check valve in one end of the grip opening inwardly thereof, a

vlaterally disposed tubular member connected to the grip and communicating therewith at the other end thereof, a tube slidable into the tubular member, a Valve seat formed in the tubular member, a ball in the tubular member, spring means holding the ball in the seat, and means for moving the tube and tubular member with respect to each other for unseating the ball.

2. A device of the class described comprising a hollow grip, a check valve in on end of the grip opening inwardly thereof, a laterally disposed tubular member connected to the grip and communicating therewith at the other end thereof, a tube slidable into the tubular member, a valve seat formed in the tubular member, a ball in the tubular member, spring means holding the ball on thel seat, and means for moving the tube and tubular member with respect to each other for unseating the ball, the inner end of the tube being formed with slots.

3. A device of the class described comprising a hollow grip, a check valve in one end of the grip, opening inwardly thereof, a laterally disposed tubular member connected to -the grip and communicating therewith at the other end thereof, a tube slidable into the tubular member, a valve seat formed in the tubular member, a ball in the tubular member, spring means holding the ball on the seat, and means for-moving the tube and tubular member with respect to each other for unseating the ball, the inner end of the tube being formed with slots, said meais for moving the tube and tubular member in rospect to each other comprising a lever rockably mounted on the grip, links pivoted tothe lever and'means pivotally engaging the links with the tube intermediate its ends.

In testimony whereof I affix my signature.
